Methods and systems for anesthetizing a portion or all of a patient's maxillary dental arch using a nasal delivered anesthetizing composition. The process generates anesthesia sufficient for facilitation of operative dentistry, endodontics, periodontics or oral surgery for teeth of the maxillary arch. The dental nasal spray process consists of inserting one or more dispensing devices through the patient's nostril and delivering metered dosages of anesthetic solution or gel into the nasal cavity. The process may utilize a single solution which is a mixture of anesthetic agents, vasoconstricting agents and other physiological inert agents or two separate solutions, wherein one solution contains the vasoconstricting agents and the other solution contains the anesthetic agents. Anesthetic diffusion through the thin walls of the nasal cavity allows for the blocking of nerve impulses originating from the maxillary dentition and surrounding tissues. Anesthesia of specific oral regions such as right versus left sides of the dental arch, anterior versus posterior teeth, and soft tissue anesthesia may be controlled through modification of the dosage volume and the selection of right or left nostril insertion and agent delivery.

Techniques are provided for controlling spinal cord stimulation (SCS) or other forms of neurostimulation. In one example, SCS treatment is delivered to a patient and nerve impulse firing signals are sensed along the spinal cord following the SCS treatment.

For example, the nerve impulse signals can be analyzed to determine whether the signals are consistent with a positive patient mood associated with pain mitigation and, if not, SCS control parameters are adjusted to improve the efficacy of the SCS in reducing pain. In other examples, heart rate variability (HPV) is also used to control SCS. Still further, adjustments may be made to SCS control parameters to improve antiarrhythmic or sympatholytic effects associated with SCS. Techniques employing baseline / target calibration procedures are also described.
